OIL-LAMP FEEDER.

SPECIFICATION forming part of Letters Patent No. 303,562, dated August 12, 1884.

T0 aZZ whom it may concern.-

Be it known that I, WILLIAM HENRY DIL- LON, a citizen of the United States, residing at Glasgow, in the county of Barren and State of Kentucky, have invented certain new and useful Improvements in Oil-Lamp Feeders, of which thefollowing is a description.

This invention relates to that class of lamps using oil which are supplied therewith from a reservoir higher than the lamp.

It has for its object to use oil conducted like gas in pipes, to raise the lamp-wick and to open the valve which admits oil thereto at one and the same movement; also, to raise or lower the wick without operating the valve.

To this end my invention consists in the construction and combination of parts form ing a lamp-feeder, hereinafter described and claimed, reference being had to the accompanying drawing, which is a vertical section, part in elevation, of a single oil-burner show- Ing my invention.

A represents the wick, and B the burner, of

usual form, adapted to screw at a into a body, G, corresponding to a lamp-body. This body 0 is provided at its lower end with a screw, 1), like a burner-screw, by which it is attached to a supply-pipe, D. This pipemay communicate with a reservoir near by, or it may be a branch of a system of pipes extending through a city or through a manufactory, the only re- 'quirement being that oil shall be supplied to the wick A. For this purpose it is usual to connect the supply pipe with a reservoir higher than the burner.

E represents the usual toothed-wheel wickfeeders, to be operated by a fixed knob, F. The shaft} 0, on which the wheels E and knob F are fixed, is square, to engage another knob, G, which is provided witha square hole, to slide longitudinally on said shaft.

(1 is a gear-wheel attached to or a part of knob G, engaging another gear-wheel, e, which is internallyscrew-threaded, engaging ascrewrod, f,whichis attached to the stem of adisk, H.

I is a valve actuated by a light spring, z, to

close the hole 76, through which oil passes from the pipe D into the body 0, therebeing a passage through the bottom of the body 0, around the stem of the disk H. The valve I is opened by means of a stem, J, which is acted upon by the disk H and the spring h, which is stronger than spring 2'.

Application filed March 21, 1884. (No model.)

The operation is as follows: By turning either knob F or G in the direction to raise the wick A, the gear-wheel d will operate the gear-wheel e to let down the screw f and disk H upon the stem J of valve I, thereby opening the valve and admitting oil to the wick, when the burner may be lighted. The spring h is strong enough todraw upon the rod f and hold the gear 6 in place on the outside of the body. By revers ing the motion of the knobs F and G, the wick will be run down, extinguishing the light, and the disk H will be raised, allowing the spring 'i to close the valve I, thereby stopping the oil from running out through the burner, which it has a tendency to do from the pressure of the head of oil in the reservoir. Then it is desirable to adjust the height of the wickwithout operating the valve, the gear-wheels d and 6 may be disengaged by drawing the knob G toward the knob F. Then the shaft 0 is free to revolve either way. The spring 9 acts between the knobs F and G, to push the latter, with the wheel d, into engagement with wheel 0.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with thesupply-pipe D, having the hole 70, the body 0, and the burner B, attached to it, and the wick-raiser E F, of the valve I, and means, substantially as described, connecting the valve with' the wickraiser, whereby revolving the wick-raiser E F opens and closes the valve, for the purpose specified.

2. The combination, with the pipe D, the body 0, the burner B, the wick-raiser E, having the square shaft 0, and knob F, of the valve I, the spring 1, operating it, the disk H, the spring h, the serew-rod f, the screw-threaded gear-wheel efand the gear-wheel d 011 the shaft 0, as and for the purpose specified.

3. The combination, with the spring-operated valve '5, the spring-operated disk H, the screw-rod f, and the gear-wheel e, of the wickraiser E, the knob F, and the square shaft 0 of the knob G, and gear-wheel d, provided with a square hole fitting said shaft, and the spring g, acting between knobs Fand G, as shown and described.
